DEEP SEA MINERALS CORP. COMMISSIONS

DOCUMENTARY-STYLE VIDEO ON THE DEEP SEA MINING

INDUSTRY

Vancouver, British Columbia – July 13, 202 6 – Deep Sea Minerals Corp. (CSE: SEAS)

(OTCQB: DSEAF) (FSE: X450) (" Deep Sea Minerals " or the " Company"), a seabed mineral

exploration and development company focused on advancing critical mineral opportunities from

the deep ocean, announces the release of a Company -commissioned documentary- style video

entitled “An Inside Look At The Deep Sea Mining Industry”, which features the Company’s Chief

Executive Officer, James Deckelman.

The video; An Inside Look At The Deep Sea Mining Industry, provides an overview of the

emerging deep sea minerals sector, the role of polymetallic nodules as a potential source of critical

minerals, and the broader strategic importance of developing diversified mineral supply chains for

the United States and allied economies.

Mr. Deckelman’s participation in the video highlight s Deep Sea Minerals’ perspective on the

opportunity for responsible seabed mineral exploration, the importance of regulatory engagement,

and the potential role that deep sea minerals may play in supporting future demand for metals used

in the electrificatio n, energy storage, advanced manufacturing, defense applications, and next -

generation infrastructure.

Deep Sea Minerals commissioned the video as part of its investor awareness, education, and

corporate communications program. The Company believes that deep sea minerals are

increasingly relevant within the broader macroeconomic context of critical mineral security,

supply chain resilience, and the need for new sources of strategic metals.

“Critical minerals are no longer just a mining issue, they are an economic security, industrial

policy, and national security issue,” said James Deckelman, Chief Executive Officer of Deep Sea

Minerals Corp. “We commissioned this video to help explain the deep sea minerals sector and why

polymetallic nodules are receiving increased attention as governments and industry look for

additional sources of strategic metals . While the industry remains early -stage and subject to ,

among other things, extensive regulatory, technical, environmental, and commercial requirements

and risks, we believe it is important to contribute to a more informed public discussion.”

Deep Sea Minerals Corp.’s strategy is focused on advancing its exploration- stage initiatives,

engaging with applicable regulatory pathways, building relationships with technical and

environmental service providers, and positioning the Company to participat e in the potential

development of a responsible deep sea minerals industry. The Company remains committed to

evaluating its activities in accordance with applicable laws, environmental requirements,

stakeholder expectations, and public company disclosure standards.
